Cordaites were gymnospermous trees with strap-shaped, sometimes very long, leaves. They played an important role in the Late Carboniferous. In the Permian they were still there, but not abundant. No fossils of Cordaites have been found later than the Autunian. We didn't find clearly recognizable fossils of this group in Les Tuilières, although Doubinger (1956) did mention them.
